Location services

Abstract

There is disclosed a mobile communication system including a plurality of cells each associated with a plurality of radio access points, and at least one mobile user connected in one cell via a radio access point, the system further including a network element associated with said plurality of cells for maintaining a neighbour list for location position determination of the mobile user, the network element including: means for generating an initial neighbour list, comprising the identity of those radio access points determined to be neighbouring the radio access point with which the mobile user is connected; means for temporarily including a candidate neighbour in the neighbour list, comprising the identity of a radio access point determined to be a potential neighbour of the radio access point with which the mobile user is connected; means for collecting measurement reports for each neighbour in the neighbour list, including the candidate neighbour; means for comparing the measurement reports for each neighbour; and means for adding the candidate neighbour to the neighbour list if measurement reports for the candidate neighbour determine that the candidate neighbour is a neighbour of the radio access point, and thereby automatically maintaining a location services neighbour list for a mobile user.

Description

[0001] The present invention relates to the provision of correct configuration parameters, such as neighbour lists for the purpose of location positioning in a mobile telecommunications network.BACKGROUND TO THE INVENTION[0002] Recently, communication networks have widely spread and are used by a continuously increasing number of subscribers. In order to cope with the challenges of providing multiple services with adequate quality for the subscribers with a limited network capacity, communication networks have to be very carefully planned in order the network can be operated smoothly while meeting all requirements of the subscribers.[0003] Mobile telecommunications systems also utilize applications, which are dependent upon the current location of a mobile station (MS) or user equipment (UE) in the network. The network, or external applications connected to the MS or MS through the network, provides services to the MS or MS in dependence upon the current location.[0004] One example ...

Benefits of technology

[0028] The invention provides a solution in which a positioning system, E-OTD for example, requires no additional actions from installation personnel, with al further actions occurring automatically. The invention provides a huge advancement in the E-OTD configurations and thus significant savings. The process and methods can be incrementally implemented.

Problems solved by technology

Not all cells in the network are suitable for this purpose.

Current techniques for both determining an initial list and maintaining such list are manual, process intensive, being an exhaustive task, and are susceptible to errors.

The problem with current EOTD configuration is that all network elements (and the NMS database objects) need to be configured manually.

Initial configurations are based on predictions, which are always inaccurate owing to the fact that the mobile environment is changing.

The modelling in planning tool is not complex enough, etc.
